Folder specific index_format

[iain truskett]

Hello,

I'm attempting to use the following (which seem logical enough for me)
to perform folder specific index formatting:


folder-hook . \
        'set index_format="%4C %4N %Z %[!%y%m%d-%H%M] %-17.17F (%5l) %s"'
folder-hook in-l-bugtraq \
        'set index_format="%4C %4N %Z %[!%y%m%d] %-14.14F (%5l) %s"'


However, they don't work. I get an error:

        %4N: unknown variable

Does anyone have a better way of formatting indexes per folder?

cheers,
